[Ed. – Well, that’s a game-changer. The question then is why Paddock stopped shooting after 11 minutes. With his cameras set up, he could presumably see what was going on outside his suite — but why would the gradual arrival of police forces cause him to stop shooting, an hour before they finally breached? When DID he (according to the working theory) kill himself?]

Police have dramatically changed their account of how the Las Vegas massacre began on Oct. 1, revealing Monday that the gunman shot a hotel security guard six minutes before opening fire on a country music concert — raising new questions about why police weren’t able to pinpoint the gunman’s location sooner.

Officials had previously said that gunman Stephen Paddock, 64, of Mesquite, Nev., shot Mandalay Bay security guard Jesus Campos after Paddock had unleashed his deadly volley at the Route 91 Harvest festival, an assault that began at 10:05 p.m.

They had credited Campos, who was shot in the leg, with stopping the 10-minute assault on the concert crowd by turning the gunman’s attention to the hotel hallway, where Campos was checking an alert for an open door in another guest’s room.

But Clark County Sheriff Joe Lombardo said Monday that Paddock shot Campos before his mass shooting — at 9:59 p.m. — and they now don’t know why Paddock stopped his attack on the crowd.
